Vishing Infrastructure and Operations

Understanding attacker infrastructure helps in detection and prevention:

Technical Setup:

  • Voice over IP (VoIP) systems for anonymity and flexibility
  • Caller ID spoofing services
  • Voice changing software
  • Call recording for information gathering
  • Script management systems
  • Customer relationship management (CRM) tools for tracking victims

Operational Patterns:

  • Call centers operating from jurisdictions with weak law enforcement
  • Shift work to target different time zones
  • Quality assurance processes to improve techniques
  • Information sharing between criminal groups
  • Money laundering networks for processing gains
